- 論文の詳細を見る
The magnon relaxation rate in the quasi-two-dimensional ferromagnets(C.H.C.H..NH.).CuCl. were measured by parallel pumping techniques fortemperatures from 1.4 to 4.2 K and for the external magnetic field applied alongthe a and b directions. The zone boundary c-magnon has relaxation rate thatdecreases for larger n and this is attributed to the increasing flattness of the dis-persion relation in the c-direction.
